On RPI4 and also in sagemcom device using WPE 2.38 it is observed that thumbnail image initially displays only half of the image, with the other half appearing black after launching the app(eg:- tg4) through controler UI
Steps to reproduce:
Launch the UIController using a browser
Disable Resident App plugin and activate WebKitBrowser Plugin
Once the app is successfully loaded, Start scrolling the carousel slider with thumbnails in the top of the Home page.
Thumbnail image initially displays only half of the image, with the other half appearing black. After approximately 2 seconds, the full image loads properly. This issue persists when scrolling to the next thumbnail. It seems like there's a delay or inconsistency in loading the image, causing a visual glitch.
@suresh-khurdiya-infosys : sorry to not comment here, I was busy with analyzing the problem and code.
So the problem can be reproduced on RPi3. I minimized the problematic test case based on the tg4 application.
Additionally with some modification of the animation time (minimize it which causes generation of only two frames of animation) , I am able to reproduce the problem also on upstream (but to observe it I have to record the test case and then watch it in slowmotion/frame by frame)
So now I am investigating how to fix the problem which can be a difficult and complex task. I am consulting it with @magomez who is an expert here.
